The route starts in Marignier from the Impasse des Perrières. A few parking spaces are available (you can also find some behind the church or near the library).
(S/E) Head towards La Möle and, fairly soon, turn right onto a wide path.
(1) At the first junction, carry on straight ahead. When you reach a cleared area, continue straight ahead and uphill (no visible signposting). A little further up, turn right at a fork, following the markings (yellow arrow). You’ll reach the Pecheux junction.
(2) Carry on straight ahead, south-west, towards L’Éponnet along a gently sloping path. After a short while, ignore a path on the left.
(3) The path runs above a few houses. Reach the Éponnet reservoir: carry on straight ahead towards Le Martinet along a small tarmac road. Not far on, take a path on the right (no signpost). After a short, steep stretch over scree, the walk is quite pleasant, with no excessive gradient and a few views. A little further up, at around 1,100 m, the gradient steepens along a route with numerous fairly short hairpin bends.
Suddenly, the path levels out almost completely. You’ll reach a wide, open spot offering a lovely view (there’s a bench here).
(4) Continue to the left, due north, following the ascent, through a less wooded area along a path that is more like a narrow track on a somewhat steep slope. A little further up, you’ll reach a wide, open meadow where the Rionffer ridge is clearly visible.
(5) The trail suddenly disappears. You should then head straight up a fairly steep grassy ridge for a vertical climb of about 60 metres (at this point, be quite careful and avoid veering too far to the right as there is a ravine). See below for further details.
Once you reach the ridge, follow a clearly visible path to the left and head for a small pass at elevation 1587.
(6) Continue straight on towards the summit of Le Môle: the route follows the ridge along a wide path, with a few steep sections in places. You will reach the Croix du Môle.
(7) Carry on straight ahead. You’ll soon reach the summit of Le Môle (where there’s a bench).
(8) Carry on straight ahead along the path, which initially winds its way up some steep slopes across grassy terrain. You will then join the main path.
(9) Carry on almost straight ahead, then turn left at the next fork: the Petit Môle is clearly visible, with chalets in the area (several routes are possible in this sector). You’ll reach the small pass near the Petit Môle, which takes about 5 minutes to reach.
(10) Turn left below a chalet and continue along a wide path (recently upgraded) that follows a gentle gradient up to the 1587-metre mark, at the crossroads you passed on the way out.
(6) Carry on straight ahead towards Marignier (via Les Granges). After a long descent, the path then continues for a short while with no significant change in elevation.
You’ll reach a clearly marked pass (with chalets) at a place called Les Granges.
(11) Carry on almost straight on towards Marignier, across the vast meadow along a gently sloping path. Enter the forest and, not long after, the nature of the path changes abruptly, plunging to the right down some fairly steep slopes for quite a while (take care).
Reach the Pecheux junction, which you passed on the way out.
(2) Continue to the left towards Marignier, taking the opposite route to the one you took on the way out (S/E).
